By Scott Sabreen, The Sabreen Group Plastics adhesion problems are widespread throughout the industry. A major contributing factor to these problems is that many plastics have chemically inert and nonporous surfaces with low surface tensions. That is, most plastics are hydrophobic and are not naturally wettable. These properties, although advantageous to the design engineer, often … Surface Wetting and Pretreatment Methods

By Scott Sabreen Problems arising from polymeric adhesion bonding are pervasive throughout the plastics industry. Two-dimensional and three dimensional products often require bonding plastic-to-plastic, plastic-to-metal, plastic-to-composite, and so on. In addition to adhesives (epoxies, urethanes, acrylics, silicones, etc.), adhesion bonding applications include adhesion of printing inks, paints and coatings, encapsulants, potting compounds, metallization, and more. … Solving the Problems of Plastics Adhesion
